ABSTRACT:
A caster-supporting device for a baby stroller includes a sleeving secured to a stroller body. A connector is inserted into the sleeving and is retained on the sleeving by engaging the window of the sleeving with the resilient retaining member of the connector. The retaining member may be pressed to disengage from the window so as to remove the connector from the sleeving. A rotating body has a fixed circular tube inserted into the annular groove of the connector and carries a caster axle which extends therethrough. A vertical pin extends through the circular tube into the connector. A sliding body can slide on the connector and has two arms which flank the connector. The arms have vertical slide slots in which a horizontal pin slides. The horizontal pin extends through the connector and the upper end portion of the vertical pin so as to retain both the rotating body and the sliding body on the connector. When the sliding body is moved to engage the opening of the connector and the locking hole of the rotating body with the spring-biased locking element of the sliding body, relative rotation between the rotating body and the connector is prevented. When the sliding body is moved to engage the positioning hole with the locking element, the rotating body is locked on the connector.
